Could you tell me what's wrong with next code? I want to get a three columns tabular where numbers are typeset with typewriter family and centred below its header. Numbers won't have any decimal part, they are integers and their decimal, binary and hexadecimal representation.

Thank you. I thought that table-figures-decimal=0 was enough. It looks like I also need to specify table-format. But why first column was well aligned without any other information?

@Ignasi: I think the default setting of table-figures-integer=3 is the reason that the first column is already centered.
